REVERS E-VALVE.

SPECIFICATION forming part of Letters Patent No. 603,103, dated April 26, 1898.

Application filed October 8, 1897.

To tu whoml t may concern:

Be it known that I, SAMUEL FORTER, a citizen of the United States, residing at New Castle, in the county of Lawrence and State of Pennsylvania, have invented or discovered new and useful Improvements in Reverse- Valves, of which the following is a specification.

In the accompanying drawings, which make part of this specification, Figure 1 is a vertical section of my invention along the line 1 1 in Fig. 4. Fig. 2 is a plan view of my improved bed-plate. Fig. 3 is a side elevation of my invention complete. Fig. 4 is an end elevation of the same. Fig. 5 is a sectional View along the line 5 5 in Fig.- 1; and Fig. 6 is a like section of the 1ced-plate, shown with the superstructure removed.

My invention, generally speaking, consists of certain improvements more especially on that class of reverse-valves covered by Letters Patent to myself, No. 57 7 ,019.

More particularly these improvements consist in an oscillating water-seal reverse-valve so constructed that the deposit of tar, dac., in the hed-plate will not interfere with the successful operation of the valve, and that such deposit may be conveniently removed while the valve isili-operation, and that all operative parts-such as links 11, shafts 7 and 8, and valve-shell e-can be removed from their positions without disturbing the outside casing.

In the several views which constitute part of this specification, 1 is a bed-plate fitted with flanged gas-apertures 1, 1b, and 1c and surrounded hy flanged edge 2. Extending laterally on bed-plate 1 from the flanged apertures la and 1 are ribs 3 3, said ribs being of less height than said `flanged edges, which are in turn of equal height with the flange 2, surrounding the hed-plate 1. EX- tending longitudinally on bed-plate l from apertures 1a and lC are ribs 3 3a of like height with ribs 3 3. When bed-plate 1 is lilled with water,said ribs are allsubmerged. Upon ribs 3 3 is supported casin g 4, provided with cleaning-doors 4fl 4:L and gas or air connection 4b. The bottom of casing4is of less size than the bed-plate 1, thus leaving an open space between casing 4 and the flange 2, through Serial No. 654.575. (No model.)

which hooks may be inserted to clean bedplate 1 of deposited tar.

5 5 are Z-irons placed laterally along the edges of casin g 4, serving to strengthen the same and also acting as a support for abrick lining for said casing.

6 is the valve-shell, provided with hooks tu 6ad to assist in its removal.

7 and S are shafts oscillating in raised open bearings 7n 7fL and 8a 8 on bed-plate 1, said bearings being of less height than flange 2, so that when said hed-plate is filled with water said bearings and said shafts are submerged.

10 10 are integral pins on valve-shell 6.

11 11 are links forged at their lower eX- tremities to shafts 7 and S and slotted at their upper extremities to receive pins 10 10 on valve-shell 6.

12 is the operating-lever bolted to one of the links 11 and provided at its upper end with weight 13, to which it is attached by chain 14, running between guide-pulleys 15 15. Weight 13 is cut away, as at 13, to avoid the base of lever 12 when said weight descends.

16 16 are the water connections of bedplate 1.

The operation of my device is as follows: Suppose the valve-shell to be in the position shown in Fig. 1, connecting apertures 1b 1c. The bed-plate,being filled with water, forms a perfect water-seal for the valve. To reverse the valve, the operating-lever 12 is thrown over, assisted in its movement by weight 13. The reversal of operating-lever 12 will cause the shaft 7 to turn, and with it links 11 11, keyed thereto. This motion would cause the valve-shell 6 to move on links 11 11, forged to shafts 7 and S, and be carried through an are until it rested in the lposition shown by the dotted lines in Fig. 1, thus connecting apertures 1a and 1b.

The following are some of the benecial features of my improved valve: The tendency in water-seal reverse-valves is for tar to collect in the bottom thereof, destroying the integrity of the water seal and clogging the operation of the reversing mechanism. It has also been impossible lheretofore to clean out such deposit while the valve is in use.

IOO

In my improved reverse-valve I elevate both the casing and the valve-shell on submerged ribs rising from the bottom of the bed-plate, leaving beneath a clean space for the deposit of tar, &c., on the bottom of the bed-plate, so rendering it impossible for such deposit t0 reach and interfere With the operation of the reversing mechanism.

The open space surrounding the base of casing 4 Within ange 2 enables a hook to be inserted and the tar removed from every portion of the bed-plate.

The valve-shell, links, and shafts may be readily removed through doors 4a 4 Without disturbing casing 4 by disconnecting lever 12 from the link 1l, to which it is bolted.

. Having described my invention, what I wish to claim is l. In reverse-valves, the combination of a bed-plate means for adapting said bed-plate to act asaWater seal; ports in said bed-plate; projections on said bed-plate of less height `than the Walls of the Water seal; a valve-shell resting on said projections; means foroscillating said valve-shell, and a casing resting on said projections.

, 2. In reverse-valves, the combination of a bed-plate; means for adapting said bed-plate to act as a Water seal; ports in said bed-plate projections on said bed-plate of less height than the walls of the Water seal; a valve-shell resting on said projections; means for oscillating said valve-shell, and a casing resting on said projections, at an interval Within the Walls of said Water seal.

3. In reverse-valves the combination of a bed-plate, means for adapting said bed-plate to act as a water seal; ports in said bed-plate; bearings erected on said bed-plate and of less height than the Walls of the Water seal; oscillating shafts yresting on said bearings; ribs on said bed-plate of less height than the Walls of said Water seal; a valve-shell resting on said ribs; links operatively connecting said shell and said shafts; a reversing-lever connected to one of said links, Vand a casing resting on said ribs at an interval Within the Walls of the Water seal.

4. In reverse-valves the combination of a bed-plate means for adapting said bed-plate to act as a Water seal; projections 0n said bedplate of less height than the walls of the Water seal; a valve-shellv resting on said projections; means for causing said valve-shell to oscillate and a casing resting on said projections; said operating parts being removable through an aperture in said casing Without disturbing the same.

In testimony whereof I have hereunto set my hand this 6th day of October, A. D. 1897.
